PROBLEM TO BE SOLVED: To provide an ID registration system capable of readily automatically registering ID information on an air pressure sensor unit according to proper timing after any of tires and wheels are replaced with new ones.SOLUTION: An ID registration system comprises: plural air pressure sensor units 20 that are attached to respective wheels of a vehicle and repeatedly transmit ID information during traveling of the vehicle according to the timing that the position on the wheel to which the sensor unit is attached becomes a predetermined position; a receiver that receives the ID information from each of the air pressure sensor units; a switch that is included in the vehicle and accepts a user's registration instruction; and a registration processing unit that, when the switch accepts the registration instruction, detects based on comparison of the rotational position information on each of the wheels, which is represented by an output signal of each of wheel speed sensors 30 during traveling of the vehicle, with the timing that the receiver receives ID information to which of the wheels each of the air pressure sensor units that has transmitted the ID information is attached, and registers the ID information, which is received from each of the air pressure sensor units, in association with each of the wheels on the basis of a result of the detection.SELECTED DRAWING: Figure 1 |
